TB-500 is a synthetic peptide derived from the active region of thymosin beta-4, a naturally occurring protein involved in cell migration, angiogenesis, and tissue regeneration. Using only the bioactive fragment improves stability and shelf life compared with full-length TB-4.
Its primary characterized mechanism is regulation of actin polymerization within the cytoskeleton, with downstream effects on stem-cell recruitment, vascular formation, and inflammatory cytokine modulation.
